BENJAMIN E. DUPONT, OF LEXINGTON, KENTUCKY.

LUBRICATOR FOR CAR-AXLES.

SPECIFICATION forming part of Letters Patent No. 389,568, dated September 11, 1888.

Application filed January 17, 1888. Serial No. 260,995.

To {LZZ whom it may concern:

Be it known that I, BENJAMIN EDWARD DU- FONT, of Lexington, in the county of Fayette and State of Kentucky, have invented a new and Improved Lubricator, of which the following is a full, clear, and exact description.

My present invention relates to lubricators of the class illustrated, described, and claimed in Letters Patent No. 368,759, which were granted to me on the 28d day of August, 1887, the object of the present invention being to facilitate the introduction of the lubricating attachment, to provide for a more equal distribution of the lubricant within thelubrieating attachment, and to more effectually guard against the entrance of grit and sand, all as will be hereinafter more fully described, and specifically point-ed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of my improved lubricator, parts being broken away and the axle being shown in section. Fig. 2 is a central sectional elevation taken on line or a: of Fig. 1. Fig. 3 is a sectional plan view taken on line 3 y of Fig. 1. Fig. et is a view of a modified construction. Fig. 5 is aperspective View of a supporting-strap employed when the box is formed without flanges. Fig. 6 is a modified form of a strap, and Fig. 7 is a perspective view of a modified construction.

In the drawings I have represented my improved form of lubricator as it appears when arranged for use in connection with a locomotivejournalbox, which box is shown at 10, the box being arranged forconnection with the pedestal in the ordinary manner. This box 10 is centrally recessed and arranged to receive a brass, 11, and at the lower portion of the box there are formed ribs or flanges 12, which have shoulders 2, as illstrated in Figs. 2 and 4. Upon this flange 12 there is seated a plate, 13, which in practice I prefer to form with lugs 14, said lugs bearing against the shoulders 2 and preventing any accidental displacement of the plate.

Two annular flanges, 16, extend upward from the plate 13, and within these flanges I mount spiral springs 17, which support acase,

(No model.)

In operation, the case 20 is filled with waste or packing and adjusted, as represented in the drawings, a supply of lubricant being introduced through the tubes 30, which lubricant, being delivered at the center line of the case, will distribute itself equally throughout the waste or packing.

From the construction described it will be seen that the case 20 may be readily inserted or removed, and that having once been adjusted to position it will not be liable to accidental displacement; and it will also be seen that, owing to the pecular formation of the flanges and 5, it will be almost impossible for dust or grit to get upon the axle or bearing.

In certain instances I might dispense with the lugs 14 by shortening the plate 13 and adjusting it so that it will rest between the shoulders 2, as represented in Fig. 4..

In Figs. 5 and 6 I illustrate straps 50, which would be bolted to the sides of the boxes, so as to extend beneath said boxes in position to support the plate 13, these straps extending entirely across the box, as shown in Figs. 1, 2, and 3; or the straps may be separated and bolted to the boxes, this form of strap being shown in Fig. 6.

In Fig. 7 I illustrate a construction wherein the case 20 is formed without side and end flanges, a frame, 70, with a downwardly-extending flange, 71, being arranged to fit upon the upper edge of the case, this construction being adopted in order that instead of renewing the case when the flanges wear out a new frame, 70, may be inserted, and another advantage of this construction being that the same case may be employed with journals of 100 different diameters.

It will also be understood that in certain cases I will use abrass or Babbitt-metal liner or gib on the ends of the lubricator, this liner or gib being employed to prevent Wear on thejournal. It will also serve to prevent wear on the 5 box, as will be readily understood.

Having thus described myinvention, I claim as new and desire tosecure by Letters Patent 1. The combination,with a case, 20, formed with housings 21, of a plate, 13, provided with flanges 16 and springs 17, arranged within said flanges, substantially as described.

2. The combination, with a locomotive journal-box, 10, having inwardly-projecting flanges 12, shouldered at 2, of lubricator-car- 15 rying plate mounted on said flanges with parts
